Validation of an enhanced pediatric vitamin D deficiency score incorporating sun exposure timing and BMI z-score: analysis in a combined cohort of children

Key Points

• This research aims to enhance the pediatric vitamin D deficiency score by including sun exposure timing and BMI z-score.
• Analyzed a cohort of children for vitamin D deficiency using the EVIDENCe-Q model.
• Incorporated weighted factors for peak UVB exposure and BMI z-scores in assessment.
• Evaluated correlation with serum 25-OH-D levels to assess predictive performance.
• The OVIDENCe-Q model with Sun + BMI weighting significantly correlates with serum 25-OH-D levels.
• Enhanced identification of children at risk for hypovitaminosis D (deficiency under 30 ng/mL).
